Excellent specimen formed by a polysynthetic growth of hematite crystals, with an exceptional brightness. Rich in faces, defined edges and a good size for the species and the locality.
Rob Lavinsky said: "Splendent, complex hematite crystals form a striking specimen from this less well-known Brazilian locale. The majestic, large crystal, with numerous amazing faces is 3.5 cm and is nearly pristine. This fine piece is complete-all-around. Choice and uncommon material from the Larry Krause dealer stock".

One of a very few tourmalines I found in this old collection with this classic combination from the 1960s or 1970s: nice brilliant lustre, glassy surface, intense color zoning between pink to green. Parallel groth, terminal rhombohedrons and a crossing prismatic pink small crystal between them. This well-known pegmatite mine was discovered in 1991 and produced very colorful tourmalines. Nice gem.
